7 PCI Bus Expansion
A quad-row socket trough-hole connector with a 2 x 2 mm (0.79" x 0.79") pitch implements the standard
32 bit PCI bus signals. The PCI-104 bus is available through the standard connector X11000.
A description of signals, including electrical characteristics and timings, is beyond the scope of this docu-
ment. Please refer to the official PCI bus and PC/104-plus specifications for more details.
Under no circumstances 5V PCI cards may be used on the MOPSlcdLX board. Only Universal and 3.3V add on
cards are permitted. V
I/O
and VCC are open (default) or set to 3.3V on the PCI bus. 5V PCI add on cards can
irretrievably damage the MOPSlcdLX board due to a short curcuit with V
I/O
or VCC. Before using a PCI add on
card please make absolutely sure that this card is conform to these requirements. The LX chipset does only
support a 3.3V PCI bus.
7.1 Configuration of V
I/O
and VCC
If it is ensured that the PCI expansion cards are types of 3.3V only zero-ohm bridges can be set.

Attention: 5V PCI expansion cards can damage the board.
Four slots are available via the connector X11000 (IDSEL, /IRQ) but only three slots are busmaster capable.
